We are looking for a meticulous and technically capable Software End-to-End (E2E) Tester to ensure the reliability, quality, and functional integrity of our end-to-end market infrastructure platform for fund distribution. Operating in a cloud-native, microservice-based, and blockchain-enabled environment, this role plays a critical part in validating that complex multi-system workflows operate seamlessly across the entire product ecosystem. The ideal candidate has strong analytical skills, hands-on testing experience in complex distributed systems, and the ability to collaborate closely with Product Owners, Business Analysts, Developers, and DevOps teams. This role is essential for delivering a robust, secure, and production-ready infrastructure to our clients. Your responsibilities include End-to-End Test Planning & Execution Design, develop, and execute end-to-end test scenarios that validate real-world business workflows across multiple microservices, APIs, UIs, and blockchain components. Build comprehensive test coverage for cross-system interactions, data flows, settlement processes, and operational edge cases. Validate integration points between on-chain and off-chain modules, ensuring end-to-end consistency and accuracy. Conduct exploratory, regression, functional, and non-functional E2E tests for each release. Test Artefacts & Documentation Create and maintain detailed test plans, test cases, traceability matrices, and test reports. Ensure that test documentation accurately reflects business processes, regulatory constraints, and architectural flows. Contribute to test data strategies and ensure availability of clean, realistic datasets for E2E scenarios. Automation & Tooling Collaborate with QA Automation Engineers to identify E2E workflows suitable for automation. Help define automation strategies for API-, UI-, and workflow-level scenarios. Work with CI/CD and DevOps teams to integrate automated E2E tests into release pipelines where appropriate. Defect Analysis & Quality Gatekeeping Conduct root cause analysis of defects found during E2E testing and collaborate with engineering squads for resolution. Validate fixes, retest impacted areas, and ensure no regressions across dependent systems. Act as a quality steward during release cycles, ensuring readiness of E2E test results before production deployments. Cross-Team Collaboration Work closely with Product Owners and Business Analysts to understand business logic and regulatory requirements. Coordinate with multiple engineering squads to align on workflows, dependencies, and integration points. Participate actively in Agile ceremonies (refinement, planning, reviews) to anticipate testing needs early in the lifecycle. Quality, Security & Compliance Focus Ensure E2E validations adhere to security, privacy, and compliance standards required in financial market infrastructures. Support operational readiness testing, including failover, resiliency checks, and disaster-recovery scenarios. Validate audit trails, event sequencing, and data integrity across components. Key skills Strong expertise in end-to-end testing of distributed systems, APIs, and microservices.
